Xiaotie Deng, Chair Professor of the Center on Frontiers of Computing Studies (CFCS) at Peking University, Director of Blockchain Committee at China Society for Industrial and Applied Mathematics (CSIAM), and Director of the Center for Multi-agent Research at Institute for Artificial Intelligence, Peking University. Before joining Peking University, he worked at Shanghai Jiaotong University, University of Liverpool, City University of Hong Kong, and York University. He received his Bachelor's degree from Tsinghua University in 1982, Master's degree from Chinese Academy of Sciences in 1984, and Ph.D. from Stanford University in 1989.


Xiaotie's main research interests are algorithmic game theory, blockchain, internet economy, online algorithms and parallel computing. His recent research focuses on equilibrium calculation, multi-agent game, internet economy, and game theory in blockchain.


Xiaotie was honored with the FOCS Best Paper Award in 2006. He is a fellow of the Association of Computing Machinery (ACM) for his contributions to the interface of algorithms and game theory (2008), and the Institute of Electrical and Electronics Engineers (IEEE) for his contributions to computing in partial information and interactive environments (2019). He was elected as foreign member of Academia Europaea in 2020, CSIAM fellow in 2021. In 2022, he won ACM SIGecom Test of Time Award.


Xiaotie has undertaken dozens of research projects as the principal investigator and has served on the editorial board of top international journals. He has chaired many top international conferences, in particular, he initiated the Conference on Web and Internet Economics (WINE) organized by the three continents in turn: Asia, Europe and the United States, and the International Joint Conference on Theoretical Computer Science (IJTCS).

Research Lab


Distributed and Automated Games And Managerial Economics (daGAME) Lab



The research subjects of lab are algorithmic game theory, Internet and blockchain economics, theory of multi-agents and deep reinforcement learning. We focuses on the methodological studies for the interactions of human with agents, in the epistemological changes with respect to acquisition of data and information, equilibrium and game dynamics among human and agents, computational and communication complexity, design and analysis of algorithms and protocols. We are especially interested in applications in the Internet market design,  analysis of incentives and cooperative competition, as well as high performance consensus, reputation system design, as well as cross-chain mechanism design in Blockchain economics and technology.
